Did the hotel keycard have anything interesting encoded in the magnetic data? I've heard stories about credit card numbers and the likes being stored in the clear on them.
- daeken 17y agoI can tell you there was nothing on tracks 1 or 2, and track 3 is purely the data for the lock itself (which I can tell you is an encrypted blob containing nothing but the data required to open the lock, although I can't talk about what exactly that is). Some properties will put data on tracks 1 or 2 if they have systems that allow you to make purchases with your keycard, but I don't know what that data entails exactly.
